help bcm4312 and b43 driver

I have being trying to get my bcm4312 with the new b43 driver for the last few days but I can't get to work. I have follow this guides
I do everything in this guides but when I try loading the b43 nothing happens. I can use it with ndiswrapper and wl but both of them have problems.

this is my lspci
04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
lspci -n
04:00.0 0280: 14e4:4315 (rev 01)
uname -a
Linux April 2.6.24-21-generic #1 SMP Mon Aug 25 17:32:09 UTC 2008 i686 GNU/Linux
dmesg when i load bcm43xx

dmesg when I load b43 shows nothing about it

dmesg for wl

I have completely remove ndiswrapper. Also the lshw -C network when I load the b43

Does the b43 or bcm43xx driver work at all with this card? Thanks in advance

There are issues with the broadcom firmware drivers in Ubuntu and Debian Etch. The following link is what worked for me. I am running Debian Etch on a laptop, and had the same results you are having now. Manually downloading the firmware drivers, and following his instructions brought my wireless card up instantly.

You should be able to successfully run this, I have an identical chip and it runs flawlessly under Slackware 12.1:

root@skamandros/home/andrew# lspci | grep Broadcom
02:00.0 Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)
0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11a/b/g (rev 01)
and running with the stock kernel for this distro:

andrew@skamandros~$ uname -r
You might be better to go straight to the b43 page:

The instructions are fairly straightforward and were all I needed to get the BCM 4312 going.
